In a fiction I am writing when one of the characters returns home to his wife he finds here sister's there as well. when asked why they've been there for the past month one explains how they are looking for real estate.
The sister who says this is well off and comes from another world which is far advance so looked down on Earth as underdeveloped. I had a line like this in mind
Melly: we thought to get some real estate out here on the boonies
Chrono: please don't refer to Earth as the boonies
I originally thought of this as it is how Mimi Houllier von Schwarzlang refers to Totori's home of Alanya, however, googleing the definition of boonies in google I got
short for boondocks.
And a google definition search for that resulted in
rough or isolated country.
Going onto thesaurus.com for Synonym of boondocks and obviously boonies is in there so looking at it's Synonyms but none are really what I'd imagine someone who's well off would say.
Back to the boondocks synonyms and i saw backwards which is what Earth would be in comparison so I looked up it's Synonyms but it's roughly the same as what the boonies had. I did think of maybe Terra Incognita but it's definition is
unknown or unexplored territory.
However Earth is known, just monitored.
So I am wondering, what word can I use for "under-developed location" which would be said by someone who is well off/rich?
NOTE: the reason why Melly would be looking to move to earth is another sister is sickly and Melly believes that an under-developed world won't have any of the ailments which could aggravate the sister's condition (with lesser ones easily curable within a few minutes)
relesate
as in one word, notreal estate
as in 2 words (removing the space made it wrong)
